There are two ways to know God.
There is the Narrative God, revealed through the pages of scripture and embodied in the person of Jesus of Nazareth. This is the story of God interacting within human history.
Then there is the Abstract God, known by rational and logical thought. We describe this God in terms of attributes. A God who is omniscient, omnipotent, and omnibenevolent. A God who is outside of time, and is immutable or unchanging. A God who is triune in nature.
The first sort of ‘knowing‘ is relational, God makes himself known in the lives of people in and through a story. The latter is ‘knowing about‘ God, as in theory and systematized propositions.
